@its tlgrtnle referat in it tlpse Entert ttnit mit uniting niet nt 'immun TO WHOM IVTMAY CONCERN: I I c.

Be it known that I, AnruUnDALLIsoN Runsnnw, of London, England, have invented a new and useful Apparatus for Sphearing or Clipping the Wool or Hair of Animals and I do hereby deiarc that the following isa full and exact description thereof, reference being had to the accompanying sheet of drawings, forming a part;of this specification.

My invention relates to :tn-apparatus for shearing sheep andiclippingithe hair of horses and-.other animals by the action of reciprocating cfutter's, which move across the edges of-xcd cutters, and cut in'both directions.

The said'iuvention consists chiefly in the peculiar construction 'and 'arrangement of such cutters, and in their combination with'ceriainnovel devices forinsuring their easy and effective working, and their ready and accurate adjustment.

The fixed cutters are formed onor rigidly attached to a metal. plate wliclris'eennected to the handle or rod whereby the apparatusnis held when in use. The reciprocating cutters are fitted to work in closej contact with the lixed cutters, and their 'edges are so formed and arranged that each pair of cutters works together with` an action similar to that of a pair of scissors. The cutters may be formed by cutting out the apertures between.l

them in the edge of a steel plate,.or each cutter may'bformed separately, and a number of theursecured in a' back or stock. y p il In using theA apparatus, the fixed cutters lie next to the skin'oi' the animal, andthcse cutters project slightly beyond the points of the reciprocating cutters, thereby preventing any possibility of injury to thc shin from contact with the latter. Thefextremite's of the cutters are rounded or curved at the back, leaving no sharp edges, whereby the animal might be accidentally injured.: The fined and reciprocating cutters are kept parallel with each other 'by guide-pins or other suitable devices, which allow oneplate to-slide freely endwise yupon the other. I i I n The reciprocating cutters are operated by means of a lever, which is pivoted to the plate or stock` of. the fixed cutters, or to some other convenient/portion ofthe apparatus, a spring being employed to draw the cutters baci: at each reeip'rocatio'n. Itis necessary that the finedl and reciprocating cuttersA should be kept closelyn4 t contact, otherwise they will not act properly, and for this purpose I attach to the apparatus an adjustable. presser-bar, whose pressure upon the, cutters is regulated byfa screw or other suitabl'edevice. To insure vthe required close contact of the said cutters,-without the friction. naturally resulting from the rubbing of one surface upon another, I employ small antifriction balls' or rollersbetween-tlie plates, andalsoupou thefoot or feet of the presser-b ar.

I construct my apparatus either tov be manipulated byhand, or provide thesame with means for connecting it with driving-mechanism, operated by'steam or other motive-power, the eonnectionbetween the apparatus and such driving-mechanism being made by cords, bands, or wires, arranged and operating in such a manner as to v allow the apparatus to be freely moved in any direction to adaptit to the position and form of the animal being sheared.

Description of the Drawings.

i Figure 1 is a view ofv one side offmy apparatus, showing the sanne constructed to be operated by a cord or band connected with any suitable drivingfmechanism.

Figure 2 is an edge view of the saidapparatns; and Figure 3 is a front view of the same. i Like letters indicate the same parts incach of the figures. The iixed cutters a and plate almay be ymade in one. piece with the shaun` orbar a2, as shown', or may he attached tothe saine .by screws, rivets, orother .suitable fastenings. The reciprocating cutters b are'fixed or formed upon the platel 11. The latter is preferably made somewhat shorter than the plate al, 'to allow the cutters b to move thcrcquircd'distance without passing beyond the edges of the-plate al. The cutters Z) are-guided by pins or studs, c, secured in thefplate al, and projecting upwards into the apertures or slot ci, which are made-'of the proper length to allow sufficient motion te the sadncutters. The friction-balls c, at therear of theplat'e In", are inadeof steel, iron, or other suiciently hard metal, and are fitted to roll in the groovcsf in the plato Zf, and upon the surface of the plate a, It wil-l be seen, by referring talig. f1, that theplatabl is only in contact with `the plate a1 for a short space beyond the bottom of the cutting-edges, and therefore moves yfreely upon the balls e. The adjustable arm orbar g is keptinplace by 'the screw-pin z, which is secured in the plate a. The rear `end of this Iblarrests in the aperture z', and by `means of thenut h, the pressure of the forward endlof lthe `said bar'upon the plate b1 is increased' or diminished. The foot g ofthenbar gvmay be'provided withx1/friction` `roller, 7', as'shown, or with a ballvsimilar to the 'balls @for the .said foot oir endotthe b'ar may bel-'extended laterally, and provided'with two or more of such b'alls or' rollers'.

The pin h also serves as'a fulcrum for theleverldnwhereby the` reciprocating cutters() are operated. `Thel boss or centre of`this-1ever lies in the aperture 132, formed in the plate b, and isprovided with a 'inger'ox-"stud` which extends into and'lflts the recess Vl in the said plate,`thc bcariz-)gisuri'aeesI ofvthis finger being rounded' to cause it tewerk freely against the sides of'the "saidlrecesa By this lever, the cutters are 4moved in thedirectiou of the arrow, the said cuttersbeingdrawn inthe opposite` directionlby the spring m, lwhich. is secnred to the .bar g, or other convenient'part o t the apparatus, and bears against th pin n projecting from the top'of the plate b1. 1 y

The cord o, attachedV to the end of the lever c,is extendedrthrough the handlep, which is made hollow, and provided with guide-pulleys, g. j The other endl of the cord is connected to a crankfleve'r or 'eccentric fixed on a driving-shafaand operated by hand, steam, or other'power.- If dcsired,'the spring n1, may he dispensed with,

and the lever c pull-ed in eachl directionby a cord"c'onnected with a-cranlc or other device. The lever-lc may Ithe said comb being extended over .the points of the cutters; The saidcomb is made.

also be operated by a cam Aor disk fitted `to turnupon a pin or stud .arranged infrontpf the handlep, and caused to rotate by a cord ori-band passing over a pulley 'connected with suitable driving-mechanism, or the lever 7c muy be provided 'with a handle, theA apparatus being then manipulated by hand like other.shearing-implements for yvarious purposes. The handlep is shown constructed ot'lmetal tubing, but' maybe formed of w'oodor other suitable material. 1 l i i l The apparatus may be' provided with a guard 6r coverA to protect the mechanism and keep the hair .or wool from becoming entangled with the same. A.comb may be attucliedutothis cover, or to the plate al, the teeth of adjustable by means of screws or other devices to regulate the length t'owhich the 'hair or vv-ool is cn-t.

What I claim, and desire to secure byrLetters Patent, isf.- Y 1. The cutters a and b, constructed, combined,'and operating, substantially as and forl the purpose set forth. 2.Thevcombination of the said cutters with the adjustable presser-bar g and lever 7c, and with orfwithont the spring m, for the purposes and substantially as sletl forth. p

Operating vthe lever 7c by means of a cord or wire lpassed rthrough the handle p, or over a rotating-cam or disk, and conneetedwth any suitable driving-mechanism, substantially as set forth.
